I did buy the asus DGX , the drivers do not work , I can not hear a difference between my on board HP ( HPE- 500f ) and the asus DGX sound card . I uploaded the drivers , most recent drivers from asus site and, I had no sound . I Uninstalled the ALC888S-VD drivers , Then installed the asus driver and no sound , I have a AMD/ATI 6870 sapphire . I just want to hear my Audio Technica ATH-M50 Headphones and my M-Audio AV 40s at it,s best. Thanks .
